To all 'whom it may concern:

Be it known that L, HORACE B'. MCCABE, a citizen of the United States, residing at Chicago, in the county lof Cook and State of Illinois, have' invented certain new and useful Improvements in Attachments for Regulating Time-Recording Registers, of which the following is a specification.

My invention relates to attachments for regulating time recording registers, and is in the nature of an improvement on other devices heretofore invented and patented by me, and particularly the time .recording reg isters forming the subjects-matter of my Letters Patent of the United States #9-1t6,858, dated January 18, 1910, and of my application for United States Letters Patent filed November 8, 1911,l Serial No. 659,125.

The primary object of my invention is the provision of an improvedI attachment for regulating time recording 4registers which shall have means for arresting during a given time the periodic change of the recording type of the register.

With the above and other Objects in View, this invention consists substantially in the construction, combination, and arrangement of parts, all as hereinafter described, shown in the accompanying drawings which form a part of this specification and illustrate the preferred embodiment of my invention, and more specifically set forth in the subjoined claims.

In the drawings, Figure' l is a side elevation of my invention showing it attached to a time recording register, and showing in outline in dotted lines an irregularly shaped frame plate; Fig. 2 is an end elevation of my invention showingit attached to a time register.

In' my former' patent and' application hereirregularly a' top plan in' referred to','provision,was made for prer venting the' operation of the recordin type of my registers during the interval of time consumed by a' workman in stamping the time' of stopping a job on one card, and

'stamping his starting time for another job ,register was locked; against operationv when :the operating handle of the register was at one end of its path of motion, and was free lto operate when the Operating handle was at the' other end of its path of motion. ,In the use of my present invention, I provide that fthe' recording type of the register may be 5 free to operate, regardless of the position of rest of the operatinghandle of the register, unless, by' the will of the operator, this new attachmentJ for regulating time recording. registers be' placed' in o eration. In my recording registers, I shi t the recording type i by the action of a' gravity pawl upon' ratchet wheels operatively` connected to the record ing type. In .my present invent-ion', I provide means whereby the gravity pawl, while free to engage in` its backward or dragging stroke, is caught inl that position and re- .tained from performing its forward operating thrust until by the actionot' my present invention it is released.

Reference numeral 10 in the drawings indicates the main frame of a time recording 11 is the inner frame plate and l2 is the These plates are secured as cap screws 13, and are held sufficiently f spaced from each other to contain operating mechanism to be later described, the spacmg being accomplished also by any suitable jl means, such as collars 14, upon the cap iscrews 13. The operating handle of the time `recording register is indicated by reference' numeral 155, and at each swing of thisv it attached to a time recording register, and

handle an'Y approximately, horizontal shaft Patelllteb ily 2l, 19144.

16, which forms one of the operating members of the time recording register, is reciprocally oseillated. Rigidly secured to the outwardly extended end of the shaft 16 is a presser finger 17. Pivoted upon a journal 18 carried between the frame plates 11 and 12, is an oscillating segment 19, toothed as at 20, and bearing a stud 21 provided with a collar 22. rIhe stud 21 is preferably disposed adjacent the pivoting journal 18 and receives the action of the presser linger 17 at each throw of the handle 15. A tension spring 23, secured at one of its ends in fixed relation to the frame plates 11 and 12, is attached to a stud 24 upon the toothed segment 19 and acts normally to hold the segment in the elevated position illustrated in Fig. 1. In this position the collared stud 21 is preferably in contact with the presser finger .1.7 When the handle 15 is thrown in either direction, the presser finger 17 moves downwardly, carrying before it the collared stud 21 and lowering the toothed segment 19 to the position illustrated in Fig. 3. A branched rocker arm 25, forming part of the mechanism of the time recording register, in conjunction with other parts, governs the operation of the gravity pawl 26. This gravity'pawl 26, by its action, controls they changing of the recording type of the re ister. Consequently, by control of 'tge' rocker arm the action of the gravity pawl 26 may be governed. In the present embod`1- ment of my invention, I provide an 'extension 27 upon the forward face of the branched rocker arm 25 and place a protruding stud 28 upon the extension 2,7.: Pivoted, as at 29, and operativelyv disposed with relation to the stud 28, is a trigger'30, having a shoulder 31 adapted to en age the stud 28. A spring member 49, fixed at one end in relation preferably to the frame plate 11, bears at its free end against a stud 50 borne upon the trigger 30 and holds'the trigger normally in a position to engage thel stud 28 when the stud-is oscillated down; wardly. Let it be noted that. the backward" draw and forward drivin thrust of the gravity pawl 26is control ed through the reciprocatoryfoscillation of the branched rocker arm 25. At the time of the backward draw of the gravity awl 26, the stud 28 oscillates with the roc er arm 25 to ami l'joiirnal 40, the friction pawl 43 being so point adjacent the shoulder 31 of the trigger 30, and the shoulder 31 will engage the stud 28 and hold the gravity pawl in its backwardly drawn position, arresting its forward thrust.- An extension 32 upon the toothed segment 19 engages an angled arm 33 upon.the trigger 30, and normally holds the trigger out of operative relation to the stud 28 when the segment is in the position illustrated in Fig. 1. However, when the segment 19 has assumed the position shown in Fig. 3, the extension 32 is withdrawn from the angled arm 33 and the trigger is left free for engagement with the stud 28.

At each throw of the operating handle 15 of the time recording register, the presser finger, acting upon the stud 21, throws the toothed segment 19 downwardly into thc position illustrated in Fig. 3, leaving the gravity pawl 26, if it has been actuated, in its backward drawn position and locked in that position by engagement of the trigger 30 with the stud 28. The driving thrust of the gravity pawl 26 is therefore delayed until the return of the toothed segment 19 into its upward position and until the extension 32 has moved the angled arm 33 sullieiently to release the stud 28 from engagement with the trigger 30. This downward throw of the toothed segment 19 is, of course, performed against the pull of the tension spring 23, the spring having a normal tendency to draw the toot-hed segment back into the upper position shown in Fig. 1. rIhe action of the capement mechanism.

lMounted upon a shaft 34 journaled for oscillation in the frame plates 11 and 12, is a, vibrator 35, preferablyl weighted at its .ends by weights 36 and 37, and slotted as at 35* for the assage of a journal to be two escapement vpinstlS and 39. A journal' fis mounted .in the-.frame-plates 11 and 12 and passes throu h the slot 35GL of vthe vibrator-.35. Itotatagly mounted upon the journal is an escapement Wheel 41, coper- ,atng with the pinsS vand 39 to oscillate tthe vibrator. Astud .42 rotrudes from andV afriction awl 43 is. eecentrically mountedfor lation upon the stud 42. ,Central upon the journal 40 is a.. circular friction dlsk 44v having a groove 45 coperi ating with the pawl 43 to'lfock the escapementv Wheel 41 and' the' disk A44; into fixed relation when the disk is actuated in, one direction, but allowing free oscillation of ion 46 central upon the shaft 40 is Xed to the disk 44 and has its teeth in engage- `ment with the teeth 2O of the segment 19. When the Segment 19 is thrown downward, the pinion 46 drives the disk 41 about the mounted as to allow this rotation ofthe disk 44. lVhen, however, the presser finger 17 recedes, at the end of the throw of the operating handle 15, from its Contact with the stud 2l, the action of the tension spring 23 nieves thej segment upwardly. The pull of the spring` 23 is conveyed through the teeth 2O of the segment 19 and thrmlgh the pinion 46 to the disk 4l. and, by reason of the frietional Contact between the pawl 13 and the disk 44, the pawl, which rides spring 23, however, is retarded by an esi'hereafter,descrip d.' This vibrator carries fthe ndisk in the opposite direction. A in-.

in the groove of the disk, binds against the disk and locks it and the escapement wheel 41 into iiXed relation. The upward pull of the spring 23, therefore, is conveyed to the escapernent wheel 41 and causes it in co-l operation with the escapement pins 38 and 39 to actuate the vibrator 35. This action of the vibrator retards the upward movement of the toothed segment 19 in practice about lfifteen seconds, though this period of time may be varied as desired by the 0011-' To :iisi'u'eg proper frictional contact at all times be"f tween the paw] 43 and the disk 44, I secire a. spring -47 upon the escapement wheel 41- and cause one of its ends to bear upon the friction pawl 43 and hold it normally in contact with the groove of the disk 44. A stud 48 protrudes inwardly, preierably from the frame plate 12, and is disposed in the pa-th of the toothed seement 19 to operate as a stop t0 the upward oscillation of the segment.

In the mechanism just described, when the gravity pawl 26 iS actuated, the trigger 30 engages the stud 28 and holds the gravitypawl 26 in'its backwardly drawn position at each swing of the operating handle 15 of the timereoording register, but, in case 'it is 'desired to operate the reg'istei` without A any retarding' action, I provide means for throwing the trigger 30 into such a position that it will not engage the stud 28. This means comprises an eccentric cam 51 mounted upon a shaft 52 which protrudes from the frame plate l1, and an extension 53 upon the trigger 30 coperating with the cam to stud 28.

throw the trigger out of the path of the An extension 54 protrudes from the side of the eccentric cam 51 and eX- tends beyond the outer face of the frame plate 12. This extension 54 bears an indicator arm 55 and a preferably square hole 56 is sunk in its outer end for the insertion of a key.

The words OE and On are placed upon the outer surface of the frame plate 11, for convenience in indicating to the op-` erator the position of the cam 51 with respcct to the trigger extension 53. lVhen it is desired to throw the trigger out of the path of the stud 28, the operator inserts his key into the key socket 56 and turns the eccentric cam 51 in a clockwise direction. Studs 57 and 58 protrude from the outer surface of the frame plate 12 and lie in the path ot the indicator arm 55, acting as stops for the movement of the indicator arm and the eccentric cam 51.

The primary object of my invention may, ot' course, be accomplished by mechanisms differing in construction from that heretoforo described. In Fig. 7 is shown such a modification, in which the collaref'l stud 21 protrudes from the side of a driving arm 59, upon which the spring member 23 acts in a manner similar to that described in the mechanism shown in Figs. 1, 2, 3, 5 and 6. The arm 59 is pivoted upon the journal 18, and the stud 21 is actuated by the presser finger 17 in the manner heretofore described. In my time recording registers, a gravity operated locking pawl 60 1s pivoted for oscillation upon the frame 10, as at 61. and is Weighted at its outer end 62. This locking vpawl 60 cooperates with a ratchet wheel 63, to prevent retrograde movement of the refco'rding type of the register, but if, when it is in locking coperation with the ratchet wheel 63, it is rigidly held in such position, itv may be employed as a detent and will arrest the change of the recording type of the register until it be releasedi-for oscillation upon its ivot. To accomplish this rigid holding oi) the locking pawl 60, I provide protruding therefrom a stud 64, and for cooperation with the stud I provide a trigger pivoted on a pin 66 and provided with a shoulder 67 for engagement with the stud 64. A sprin'o member 68 fixed at one end in relation to the pin 66 bears at its free end against a stud 69 upon the trigger 65, and tends tofdraw thetrigger against the stud 64. An extension 70 upon the pivoted arm 59 bears a lateral stud 71, which coperates with an extension 72 of the trigger' 65 to maintain the trigger out of operative contact with the stud 64 when the arm 59 is in the position shown in full lines in Fig. 7.

Vhen, however, the operating handle 15 of the recording re ister is actuated, and the presser finger 17 y its action upon the stud 21 has thrown the pivoted arm 59 into the position shown in dotted lines in Fig. 7, no operative contact is had between the stud 71 and the extension'72 of the trigger, which leaves the spring member 68 free to perform its action of drawing the trigger into operative contact with the stud 64. Until the stud 71 again contacts with the extension 72 of the trigger, the locking pawl 62 is rigidly held in its locking engagement with the ratchet wheel 63 and arrests the change of the recording type of the register. As was stated above, the spring member 23 acts normally to draw the pivoted arm 59 upwardly from the position shown in dotted lines in F ig. 7 to the position shown in full lines. For the purpose of delaying this upward oscillation of the arm 59, I provide a piston casing 73 having a small air vent 74 in its closed upper extremity, and provided with a reciprocating piston 75. The piston 75 is connected by a link 76 to the free end of the arm 59, and is also valved to admit of its ready downward movement but in such manner that the valve is closed during upward movement. Preferably, I construct my valve by centrally boring the piston, as at 7 7, and enlarging the bore 77 into a ground seat 7 8 for engagement with a ball 79. By the use of this piston, the u ward oscillation of the arm 59 is retarded or the length of time which it takes for the air imprisoned by the valve action of the piston to pass from the piston casing 7 3. A closure 7 3a upon the upper extremity of the piston casing 73 forms a stop for the upward oscillation of the piston 75 and the arm 59. A band or stirrup 80, shown in F ig. 8, is secured to the frame plate 11 and serves to hold the piston casing in its proper position.

Fig. 4 is an elevation of the end of the time recording register opposite the end to which my improved attachment for regulating is secured. In the registers forming the subject matter of my Letters Patent of the United States dated January 18, 1910, and my application for Letters Patent tiled November 8, 1911, Serial No. 659,125, I provided a cam (designated in that application by reference numeral 139), to which the op` erating handle of the register was attached, for cooperating with other parts of the mechanism therein described to lock the recording type against change at the time when the operating handle was at one end of its swing. Vhen the operating handle was at the opposite end of its swing, a. portion of the surface of the cani at one end was beveled off to release the locking mechanism. In Fig. 4 of my present invention, this cam in indicated by reference numeral 81, and the end portion which was beveled away is indicated by reference immoral 82. Fig. 4 is inserted in this application for the purpose of showing that in the operation of my time recording registers above mentioned in cooperation with my present invention, I bevel away, as at 83, the opposite end of this cam 81, in orderJthat the mechanism cooperating with the cam 81 may at the end of each swing of the operating lever 15 be released from its locking action upon the recording type of the register.

In the drawings forming a part of this `i-..specitication are 'shown many parts of my time recording registers which are not here described in detail, for the reason that they form the`subjcct matter of my Letters Patent of the United States No. 946,858, dated January 18, 1910, andmy application for United States Letters Patent tiled November 8, 1911, Serial No. (559,125.

ln the time recording registers heretofore patented and invented by me and hereinabove referred to, the changing of the recording type of the register' was accomplished by the periodic actuation of an electric engine. designated in Figs. 1, 3, 4 and T ot' this presentapplication by reference numeral Ht. The action of the electrical taigiue S-lwas conveyed through various na-rhau'ral parts lo the gravity pawl QG, which was drawn backward by the engine Should a workman insert his card in the time recording register and, by swinging the opera-ting handle 15, take an impression on the card just before the actuation of the electrical engine 84, the gravity pawl 26 will perform its backward pull or draw when the engine is actuated, but may, by the action of my present invention, be restrained from accomplishing its forward driving thrust for a period of time of suflicient length to allow the workman to print a new card after printing his old card, before any change is made in the recording type of the register. rllhe exact period of time in which the gravity pawl 26 is restrained from its forward driving thrust may be either longer than, shorter than, or the same as, the period of energizing of the engine; the relation between the two periods being generally immaterial if the workman is afforded sufficient time in which to print two cards. l/Vhen the action of my present invention is complete, however, the mechanism of the recording register will be released to allow the change of the recording type.

In the present embodiment of the invention the gravity pawl Q6 is shown in Figs. l, 2, 7 and 8 at the end of its thrusting or driving stroke, while in Fig. 3 it is shown at the opposite end of its path of movement or at the end of its drag stroke and in position to perform its thrust. The indicating and print-ing wheels of the register (shown most clearly in Fig. 2) are designated by reference numerals 8G, 87, 88 and 89.' They are mounted for rotation upon co-axial shafts, and upon the opposite ends of the respective shafts are ratchet wheels 63, 91, 92 and 93. One end of the gravity pawl QG contacts with the ratchet points of the wheels G3, 91, 92 and 93%, to rotate them step by cstep, which rotation accomplishes the simultaneous rotation ot' the number wheels 86 to 89 inclusive. The indicating and printing wheel 86 is mounted upon the same shaft as the ratchet wheel (33, and the pawl .26 drives the ratchet wheel G3 and the wheel 86 once at each stroke of the pawl. During nine slrolces of the pawl it is prevented, by means of a side disk 94 secured tothe ratchet wheel (53, from contacting with the ratchet wheel 91, but at the tenth stroke of the pawl a notch in the side disk 9-1- allows the edge of eating and printing wheels.

the pawl 26 to drop sufficiently to engage the teeth of the ratchet wheel 91y whichv will cause a movement of both wheels 86 and 87. A side disk 95 secured to the ratchet wheel 91 withholds the pawl 26 from engagement with the ratchet wheel 92 during nine steps of the ratchet wheel 91, but at the tenth step or partial turn of the ratchet wheel 91 a notch in the side disk 95 allows the gravity pawl 26 to drop sufficiently to engage the ratchet wheel 92 which causes it to move wheels 86, 87 and 88. One of the notches vin the ratchet wheel 92 is cut deeper than the others in order that at every tenth movement of the ratchet wheel 92 the pawl 26 may drop sutli- Ciently to engage the ratchet wheel 93 which will cause movement of all four of the indi- The edge of the gravity pawl 26 is broken for the purpose of causing it to engageproperly with the ratchet wheel and side disk described. During the backwa-rd stroke of the pawl `it rises lupon one point of the ratchet wheel 63 and drops into the notch beyond it, and during the forward or thrust stroke the pawl engages the toothof the ratchet and turns the wheel. The same action of the pawl is had with relation to each of the ratchet wheels in turn as the side disks permit the drop of the pawl to engage the various ratchets. Motion is communicated to the pawl 26 from the electrical engine 84, the

communicating means being a lever 96 secured to the armature plate 97 of the electrical engine 84 and a link 98 joining the free end of the lever to the branched rockerarm 25. The gravity pawl 26 is pivoted at one of its ends to the rocker-arm 25. A spring- 99 is connected to the lever 96 to draw it normally into the position shown in Figs. 1, 2, 7 and 8, while the electrical engine at` each actuation operates to draw the lever 96 into the position shown in Fig. 3.

In the accompanying drawings and in the foregoing description arenset forth the preferred embodiment of my invention, but it is'obvious that one skilled in the art may make modifications of the same without departing from the principle of the invention.
